These stocks requires no modification to your AK.  Fits all stamped AK's from China, Russia, US (1.5mm thick sheet metal receivers). Romania, Egypt, Hungry, E. Germany, Russia, US (1mm  thick Sheet metal receivers).

All ACE parts in these stock kits are precision CNC machined in the USA from 6061 T-6 Heat treated aluminum. They are then aluminum oxide blasted for a mat finish then type 3 mil-spec anodized for a durable and corrosion free finish. The folding stock mechanism is machined from 7075 T-7 Al which is pound for pound stronger then steel! And then receives the same hard anodized finish. We use Delrin for the top bar and brace on the AKFX skeleton stock (even though it is more expensive than aluminum) so that the operator will have a more comfortable cheek weld. Delrin is an engineered plastic that is extremely strong, can be machined and it will insulate the operator's face from vibration and extremes in temperature.
